Fig. 2is a-:sectionalview or the apparatus detached, in

the line mm, Fig. 1. Fig. 3 is an enlarged view, in perspective, of adetached portion of the apparatus, as presently to be explained; andFig. 4 is a longitudinal vertical sectionalview of a flue-boiler, and ofmy improved apparatus applied thereto.. In the ordinary .mode ofutilizing soft or Jhitu'minous coal as a fuel, the waste by smoke land'u'nconsumed gases is enormous. This is especially the case onrailway-locomotives, ,iwliere the strength of the blast is such as todraw through and blow ont not only unconsumed gaseous products, but alsosolid matter in considerable quantities. As a means of avoiding suchwaste, or a considerable part of it, 1 employ a gas-producer, to convertthe ,solid fuel into gaseous fuel, arrangesnch producer on the tenderorfother {convenient part of the train, and conduct the lg ases andsmokedirectly therefrom to the firebox, and. there ignite it in'connectionwith a' supply of oxygen. 1 have also devised an improved apparatus forheating and burning the 'fire-boxB' I arrange the apparatus presently tobe described, or other suitable gas-burning and air-supplying'appa-,r'atus suitable for burning the gases, smoke, given'ofl by thegas-producer. ,On thep u Haltwans, Pl'il TSBURG, P NNSYLV NIA,"Assienoa'ro "artisans-HEN Yw rAgrfrsnson, AND JAMES inwmor sAMnrL cE,

This drum 6 has a long narrow slotor equivalent perforations, e, "Fig. 3,' fdr the introduction into thefire-box of the smoke, gases, &c., from the gas-producer in athin sheetor small jets at the desired point of ignition. The air necessary tosupply oxygen at this point of ignition isintrodueed from without, andconducted along in 'or'back and forth inside of the fire-box by a pipe,.9, arranged with reference to being heated in like manner as alreadydescribed with reference to the pipe 0, and so as to heat the ingoingair, which then passes into the cross-pipe or drum 1?, which latter isarranged in like manner as the drum 6, and has alike slit or series ofperforations, t", as also shown in Fig. 3. These exit-passagesfor theheated gases and air are in such juxtapoand gases shall-quickly andreadily commingle, and then, being ignited, will result in the thegrate-bars; a thedainpers; a. ,the chargshown in all thefigures,takesthe-gas, smoke,

then, entering the flue b, continues its work as a heating agent with aminimum percentage of loss. Fig. 4 is intended to show merely onewaytofusing the apparatus described in connection with a flue-boiler.But the kind or class of boiler, or the kind or form of heatlng-chamberor fire-box, in or in connection with which the apparatus is used, orthe purpose to which the heat, when generated, is to be applied, is nota material element in this employed.' Instead-of air, any oxygen-bearing gas or vapor-may be employed in "In:

manner, and for the purposes of this case I include the latterinthe termused. Also, with stationary heaters, where natural gas is available, theproducer may be dispensed with, and the natural gas be conducteddirectly into the pipes c and drum e. with the operation and-resultabove described.

I claim herein asmy in'vention 1. The pipes c s and sli'tted orperforated cross-tubes or drums-e i, arranged in the firespace of aheating apparatus, with the drums opposite the exit-flue, and the pipesin the line of draft between the drums and exit-flue, substa'ntially asset forth. 7

2. A gas-producer, a gas-heater, and burner apparatus connectedtherewith, and an air heating and supply apparatus for perfecting thecombustion of the gas, arranged on and combined with a locomotive andtender, substantially as set forth.

In testimony whereof I have hereunto set my hand.
